I thought this was a routine update. I installed it. Many problems. No benefits. Why? I called cust no service and tech no support and they said there is nothing they can do. They can't fix anything and they can't undo what they called an upgrade. Are they kidding? I called for a credit on a new phone. The rep said no and would not let me speak with a supervisor. I then got a call asking me to rate the service from 0 to 10. It was very easy to press 0.
